Place a virtual TV screen in the 3D world playing a Veo 3.1 video.
AI agents use place_world_tv to create or update resources in Worldlabs — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Worldlabs environment.
The tool creates and places a new virtual object (a TV screen) within the 3D world, which is a reversible data modification. This is Write-category behavior rather than Read (no retrieval-only operation), Execute (not running arbitrary code/commands with unpredictable effects), or Destructive (the action is reversible). The modification affects the world state but can be undone through deletion or replacement.
From the tool's definition Tool description states 'Place a virtual TV screen in the 3D world playing a Veo 3.1 video' — this creates and places a new object (virtual TV) in the 3D world, modifying the world state.
Documented attack patterns abuse exactly the kind of access place_world_tv gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Worldlabs, and nothing reaches the server without passing your rules. This is the rule we recommend for place_world_tv:
{
"version": "1",
"default": "deny",
"tools": {
"place_world_tv": {
"limits": [
{
"counter": "place_world_tv_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}place_world_tv stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Place a virtual TV screen in the 3D world playing a Veo 3.1 video. It is categorised as a Write tool in the Worldlabs MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Worldlabs MCP server in PolicyLayer and add a rule for place_world_tv: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Worldlabs. Nothing to install.
place_world_tv is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the place_world_tv rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for place_world_tv. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
place_world_tv is provided by the Worldlabs MCP server (sandraschi/worldlabs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Worldlabs, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
